<P><FONT size="5">I suspect your personally owned modem may have been incorrectly set up by Spectrum.&nbsp; I suggest you first verify the modem's MAC ID on your account record, then call in to the Tech Help line.&nbsp; Ask the agent to confirm they show your device's model number is CM500, the MAC ID is exactly as shown on the modem, and ask him to send the boot file again.&nbsp; After the restart, look at the signal levels page to see if your modem finally has all four US channels running at levels less than +51 dBmV.&nbsp; That's the goal for this round! &nbsp;</FONT></P>Wed, 09 May 2018 02:48:14 GMTkarlbeckman2018-05-09T02:48:14ZMust reboot modem to regain speedshttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149961#M49875
<P>Approximately&nbsp;once every three days I notice my internet browsing speeds slow to a crawl. The internet still technically works, but the speeds are atrocious. My download rate is about 2 Mbps but my upload remains perfect at 20 Mbps. This issue has been occuring for about six months now. The issue is immediately resolved once I power cycle my modem.</P><P>&nbsp;</P><P>On the 300 Mbps/20 Mbps plan. The&nbsp;modem is a Netgear&nbsp;CM500-100NAS. I've used it for four months. Prior to this, I had a TP-Link TC-7620 that I used for about 1.5 years. The reason I stopped using it? Yep, you guessed it, because of the issue I just described. I thought it was my modem, but sure enough it must be something else.</P><P>&nbsp;</P><P>Here are the logs from the last time this happened. I will be obtaining the logs every time this occurs from this point forward. Any help would be <U><EM><STRONG>much appreciated</STRONG></EM></U>.</P><P>&nbsp;</P><TABLE><TBODY><TR><TD><P><STRONG>Time</STRONG></P></TD><TD><P><STRONG>Priority</STRONG></P></TD><TD><P><STRONG>Description</STRONG></P></TD></TR><TR><TD><P>2018-3-20, 23:46:34</P></TD><TD><P>Critical (3)</P></TD><TD><P>SYNC Timing Synchronization failure -

<P>You have a coax issue somewhere...loose connections, chewed or water logged coax...that is causing your problems. It is not the modem. The upstream levels are too high and you should (probably) have 4 channels instead of 2. At 52dbmv, the upstream is at it's absolute top end and is causing the slowdowns and timeouts.</P><P>&nbsp;</P><P>Can you describe the cable run from the main line to your house to each outlet (splitters, amps, length of runs, etc.)? Have you had a tech out in the past 6 months and what was their diagnosis?</P>Mon, 26 Mar 2018 15:51:39 GMThttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149962#M49876reds911852018-03-26T15:51:39ZRe: Must reboot modem to regain speedshttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149974#M49878
<P>Thanks for the help!</P><P>&nbsp;</P><P>It's a townhome, so I am not exactly sure on the specifics of the coaxial connections, but I will try my best.</P><P>&nbsp;</P><P>4 units in the building. There are two coaxial connections in my entire unit. I'm fairly certain there is not a splitter in play. If so, it is buried in the wall somewhere that I cannot see. I'll try to find where the coaxial comes into the unit and see if there&nbsp;are&nbsp; 1 or 2 lines.</P><P>&nbsp;</P><P>I haven't had anyone out recently. Every time I have in the past, I am told there is no issue, and the person leaves within 5 minutes. It's very frustrating.</P><P>&nbsp;</P><P>IMO, the outside line is&nbsp;the culprit&nbsp;and water is to blame. I can't be exact, but it seems that every time it rains I experience these issues.</P><P>&nbsp;</P><P>Yeah, strange that there are only 2 upstream channels. There certainly used to be 4.</P>Mon, 26 Mar 2018 17:25:26 GMThttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149974#M49878bios2018-03-26T17:25:26ZRe: Must reboot modem to regain speedshttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149979#M49879
<P><FONT size="5">Thanks for including the event status and signal level reports in your posting.&nbsp; We need both to diagnose the kind of problems you are experiencing.&nbsp; When you have both TV and internet service, your cable modem should be on the first 2-way splitter coming in from the drop cable.&nbsp; Anything else causes high loss and poor signals both up and down.&nbsp; </FONT></P><P><FONT size="5">Your modem says it has very high error counts on two of the downstream channels, DS28 and DS32.&nbsp; That points to ingress interference from over the air broadcast TV stations which usually is caused by corroded or loose connectors along the trunk lines or drop cable that is abraded and letting water in.&nbsp; The location of both the signal leak and water leaks could be either overhead or underground; subscribers get the same bad results. &nbsp; </FONT></P><P><FONT size="5">You can look up those local TV stations at <A href="http://www.antennaweb.com" target="_blank">www.antennaweb.com</A>, but&nbsp; you can't always trust the channel numbers the stations ID with anymore.&nbsp; If you'd rather just post your ZIP Code, we can check all stations in the area for you.&nbsp;</FONT></P><P><FONT size="5">You will need to have Spectrum send out a home service tech to verify the poor signal quality.&nbsp; Print out a copy of the event and signal logs for the tech, so he can see what the modem is complaining about.&nbsp; Regardless of what any phone tech support person says, DO NOT reset the modem for at least twelve hours before the service person is scheduled to arrive, and DO NOT let them try to cancel your home service call by claiming that they don't see a problem at their end!&nbsp; </FONT></P>Mon, 26 Mar 2018 20:19:35 GMThttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149979#M49879karlbeckman2018-03-26T20:19:35ZRe: Must reboot modem to regain speedshttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149980#M49880

<P>If you are only getting internet service, your modem should be connected directly to the incoming drop cable, with no splitter at all.&nbsp;&nbsp; Did I miss seeing your ZIP Code?</P>Mon, 26 Mar 2018 21:10:16 GMThttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/149984#M49882karlbeckman2018-03-26T21:10:16ZRe: Must reboot modem to regain speedshttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/151878#M50316
<P>Wanted to follow up and say that a Spectrum tech came out about a month ago and let me know an external connection was lose and allowing moisture in. Since he tightened it up I have had zero issues...</P><P>&nbsp;</P><P>...other than still getting 2 upload channels. Anyone know if that is expected behavior with the CM500? Admittedly, I cannot remember if I ever got 4 upload channels, but the modem certainly supports 4.</P><P>&nbsp;</P><P>I've called Spectrum a few times about this, even spoken with Tier 2, and I imagine the looks on their faces are like a deer in headlights to my question. Literally no one knows what I am talking about. Don't really understand how that is possible.</P>Tue, 08 May 2018 14:45:57 GMThttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/151878#M50316bios2018-05-08T14:45:57ZRe: Must reboot modem to regain speedshttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/151900#M50318
<P><FONT size="5">I suspect your personally owned modem may have been incorrectly set up by Spectrum.&nbsp; I suggest you first verify the modem's MAC ID on your account record, then call in to the Tech Help line.&nbsp; Ask the agent to confirm they show your device's model number is CM500, the MAC ID is exactly as shown on the modem, and ask him to send the boot file again.&nbsp; After the restart, look at the signal levels page to see if your modem finally has all four US channels running at levels less than +51 dBmV.&nbsp; That's the goal for this round! &nbsp;</FONT></P>Wed, 09 May 2018 02:48:14 GMThttps://forums.timewarnercable.com/t5/Connectivity/Must-reboot-modem-to-regain-speeds/m-p/151900#M50318karlbeckman2018-05-09T02:48:14Z
